Description |
Italiano: Questo due strumento ha forma parallellepipeda ed un quadrante, che occupa tutta la superficie frontale, ricoperto e protetto da una lastra in materiale trasparente La scala di misura di forma ad arco di circonferenza, con zero a sinistra, permette misure di correnti continue comprese tra 0 e 50 A, con tacche ogni 2 unità ed indicazione numerica ogni 5 La lancetta indicatrice è imperniata nell'angolo in basso a destra del quadrante e in prossimità di questo punto è inserita una vite per la correzione dello zero Sulla parete posteriore troviamo due connettori per i collegamenti elettrici al circuito da misurare Lateralmente sono inseriti due dispositivi a vite che permettono il posizionamento dello strumento su di un quadro di controllo più generale.
Misura della quantità di corrente continua circolante in un circuito elettrico
